作者薛栋（2019）在《相山火山熔岩亚型和次火山岩亚型铀矿床流体包裹体特征比较》一文中研究指出：相山铀矿田是我国重要的火山岩型铀矿田,区内分布二十多个铀矿床,主要分属三个种类:火山熔岩亚型、次火山岩亚型及隐爆角砾岩型,以前两者为主,隐爆角砾岩仅有一个巴泉矿床。火山熔岩亚型和次火山岩亚型铀矿床在流体包裹体特征之间的异同,可能给出成矿的相关信息,可为成矿过程探讨、矿床成因分析和区域找矿提供参考。选取火山熔岩亚型中的邹家山矿床、云际矿床、居隆庵矿床和次火山岩亚型中的山南矿床、沙洲矿床作为研究对象,在已有工作基础上,通过野外地质调查、薄片显微镜下鉴定、扫描电镜、流体包裹体测温等,对流体包裹体特征进行比较,并对相山成矿模式进行探讨。主要取得了以下认识:（1）相山铀矿田流体包裹体均一温度变化范围为160400℃。峰值分布为:邹家山122162℃、242298℃,云际160187℃、227287℃;居隆庵220260℃;山南220.5240℃、261.7298.2℃;沙洲201240℃、280298℃、325.6340℃。两亚型均一温度值均可分为2到3个峰值范围,且有所重叠,火山熔岩亚型温度较低,次火山岩亚型温度较高。相山铀矿田流体包裹体盐度变化范围从0.8822.00wt%,峰值分布为:邹家山2.983.28wt%、3.884.18wt%,云际3.243.54wt%、3.844.14wt%,居隆庵1820wt%;山南5.977.97wt%、9.9710.97wt%,沙洲11.214.2wt%。火山熔岩型和次火山岩型盐度具有明显差异,火山熔岩亚型较低,次火山岩亚型较高。相山成矿流体密度变化范围在0.61.1g/cm3之间。邹家山矿床0.650.95g/cm3;云际0.750.95g/cm3;居隆庵0.51.15g/cm3;山南0.641g/cm3;沙洲0.701.05g/cm3。两者密度变化较小,整体为中低密度流体。（2）相山铀矿田平均成矿压力峰值及相应深度:邹家山340.3×105Pa、1.132km,204.57×105Pa、0.68km。云际379.55×105Pa、1.26km,721.12×105Pa、2.4km。居隆庵139.3×105Pa、5.15km。山南506.8×105Pa、1.6km,781.8×105Pa、2.6km。沙洲619×105Pa、2.0km,634×105Pa、2.11km,914.4×105Pa、3.0km。成矿压力和成矿深度各个矿床差异较大。总体来看,火山熔岩亚型成矿深度较浅,次火山岩亚型成矿深度较深。（3）两亚类铀矿床包裹体气相组分大致相同,主要为H2和CO2,成矿流体来源一致,且均处于还原环境。（4）根据以上流体包裹体特征研究,认为相山矿田铀矿床成矿主要经历了2期次成矿。早期成矿温度较高,主要与火山期后热液为主,以次火山岩亚型铀矿床为代表。晚期成矿温度较低,与深大断裂加温、盆地脱水形成的热液密切相关,受邹—石断裂影响,以火山熔岩亚型铀矿床为代表。早期铀成矿作用常被晚期铀成矿作用叠加。
